With pressure-treated lumber, it is essential that you use hot-dipped nails to prevent the corrosion caused by the chemicals used in the lumber. Nails intended for outdoor use are often galvanized or "hot-dipped" with a coating of zinc to improve their weather-resistance. Stainless steel is also used for outdoor applications, though stainless steel nails are considerably more expensive than zinc-plated nails. A nail that is uncoated in any way is often called a "bright" nail. Never let belts run against belt guards or other obstructions. Nails can also be coated with phosphate to improve their holding power. perform in a variety of industries worldwide and are available in a variety of sizes. Many construction nails are coated with a thin layer of vinyl, which acts as a lubricant when driving the nail. Most construction nails are steel, often with some kind of surface coating. Or, nails can be galvanized or plated with zinc or another metal. Nails can be made from a variety of metals, including ordinary steel, stainless steel, brass, copper, or aluminum. Nails are available in different sizes and shaft configurations to maximize their holding power in different applications.
The holding power of a nail derives from the simple friction of the displaced wood fibers gripping the shaft of the nail. When driven into wood, the shaft of a nail pushes apart wood fibers as the point penetrates. The physics of how nails work are simple. The wrong nail for the job can result in a weak connection and/or damage to the wood. The right nail has the right strength, size, and other design features for the job at hand. While a hammer and nail may seem as simple as it gets, do you know which nail to use in every application? Just as hammers require some knowledge for using them effectively, nails have right and wrong uses.
Fire-forged brass nails in Egypt date back to 3400 BCE, and nails have been a construction main-stay ever since. Like peanut butter and jelly, it's a classic combination that has been around forever. The Spruce Home Improvement Review Board.
